make it possible to enable RC override on non-HIL setups 

this makes it possible to allow a GCS to override RC input values for
non-HIL setups. This gives a way for a GCS to set an arbitrary switch
value, or set a precise PWM value for any control.

//////////////////////////////////////////////////////////////////////////////
// RC override
//
// ALLOW_RC_OVERRIDE OPTIONAL
//
// This is for advanced used only!
//
// If you enable ALLOW_RC_OVERRIDE then a GCS will be able to
// override RC input values using a MAVLINK_MSG_ID_RC_CHANNELS_RAW
// message sent to APM. This allows the GCS to precisely control
// all PWM values as seen by APM, which means it can set any switch
// position, or set a precise control value. Do not enable unless you
// really know what you are doing!
//
//
// Do not remove - this is to discourage users from copying this file
// and using it as-is rather than editing their own.
